代码：

package com.yql.test.enumtest;

public enum SeckillStateEnum {
	SUCCESS(1, "秒杀成功"), END(0, "秒杀结束"), REPEAT_KILL(-1, "重发秒杀"), INNER_ERROR(-2, "系统异常"), DATA_REWRITE(-3, "数据篡改");
	private int state;
	private String stateInfo;
	private SeckillStateEnum(int state, String stateInfo) {
		this.state = state;
		this.stateInfo = stateInfo;
	}
	public static SeckillStateEnum getStateInfo(int index) {
		for (SeckillStateEnum state : values()) {
			if (state.getState() == index) {
				return state;
			}
		}
		return null;
	}
	public int getState() {
		return state;
	}
	public String getStateInfo() {
		return stateInfo;
	}
	
}

测试代码：

package com.yql.test.enumtest;

public class SeckillStateEnumTest {

	public static void main(String[] args) {
		System.out.println(SeckillStateEnum.getStateInfo(1));
		System.out.println(SeckillStateEnum.getStateInfo(1).getStateInfo());
		System.out.println(SeckillStateEnum.SUCCESS);
		System.out.println(SeckillStateEnum.SUCCESS.getState());
		System.out.println(SeckillStateEnum.SUCCESS.getStateInfo());

	}

}

结果：

SUCCESS
秒杀成功
SUCCESS
1
秒杀成功
